COMPUTER SYSTEMS

State of the in the area of recurrent neural networks, that have features of both deterministic and open dynamic research systems, is analyzed. Review of structure, work principles and training methods of known recurrent neural network models is given. Problem of resources, required for their training, is discussed, and new approach to its solution is considered. New model of open recurrent neural network, and non-iterative method of its training, are proposed. Figs.: 9. Refs.: 45 titles.

The works is devoted to consideration of the problem on creation of the new economy, responding to development of information-intelligent society. The tendencies of the economical systems development, factors determining of the new economy appearance and essential distinctions of the new economy from existing. Functioning the economical system is discussed in the aspect of the following basises: functionally-resourced, organization-managing and industrial-financial demand and suggestion, information-communication and intelligent. Refs.: 17 titles.

Materials of physico-mathematical theory of hyper-random phenomena oriented to description of statistically unstable physical phenomena are presented in the generalized article. Study questions of the world are discussed. Different measurement models are researched. Hypothesis of statistical unpredictability and hypothesis of hyper-random set up of the world are analyzed. From these hypotheses follow that cognition horizon is restricted by boundaries of unpredictable changes of researched physical phenomena and of statistical conditions of their watches. Figs.: 5. Refs.: 42 titles.

In this work, the approach to adaptation of known descriptions of conceptual graphs with reference to visualization of the formalized representation of naturally-language statements for inflectional languages is considered. Figs.: 7. Refs.: 5 titles.

It is given a brief introduction to probabilistic dependency models in a class of acyclic directed graphs (DAG). It is compared expressiveness of different special subclasses of these models. A class of "mono-flow" models (where instruments factors of common effect are mutually independent) is thoroughly examined. It is rigorously derived relations between structural and Markov properties of ‘mono-flow' models. Spurious association phenomenon is shown. The proposed analytical instruments are useful for constructing reasoning schemes and learning model structure from data. Figs.: 5. Refs.: 22 titles.

It is discussed one from approaches for providing viable development. SSMD on the base of using interactive methods of intelligent analysis of data of the past activity <SSMD+Object>. The corresponding set of mechanisms and instruments that broaden intelligent ability of the traditional SSMD is proposed to consider as problem-oriented content analysis of "history" activity of association. Tabl.: 3. Figs.: 2. Refs.: 7 titles.

The article is devoted to the methodical questions for the support of making management decisions at the prevention and soling conflict situation process. The netting model for the estimation of level security of the potential hazard object was used. The methodical approach and the algorithms to the selection of the rational strategy for the level security advancement of the potential hazard object was set. Fig.: 1. Refs.: 14 titles.

The quantity value of the user interface characteristics in the task of manual on the base of applying model GOMS is discussed. The results of counting are given, the pecularities of the estimation of the intellectual load on user GOMS model are discussed. Tabl.: 1. Figs.: 3. Refs.: 6 titles.

In article the technique of definition of dimension and an error of the decision of system of the linear equations of mathematical model of an additive mix useful and casual signals of system of protection military and other important objects providing correct definition of parametres of a useful signal is considered. Tabl.: 1. Figs.: 4. Refs.: 11 titles.

Main needs of multimedia and time-sensitive applications, overview of timer chipsets, analysis and estimations of system time services are given in the article. Research is aimed to use in multimedia and time-sensitive applications. Tabl.: 5. Refs.: 2 titles.

In the paper the structure of type model of life cycle of the difficult programmatic systems is discussed. Intercommunication of some international standards in the field of information technologies and basic processes of life cycle of information systems is presented. Refs.: 24 titles.

History of Internet in the USSR and Ukraine: main stages of the development / Grinchenko T.O., Polumienko S.K. // Mathematical Machines and Systems. - 2009. - N 3. - P. 151 - 156.

In the article the basic stages of development the Internet in the USSR are described. The special attention is paid on formation the Internet in Ukraine as a constituent part of world process of development the Internet. Basic principles of functioning of the Internet are described. Refs.: 7 titles.

LARGE SYSTEM SIMULATION AND MANAGEMENT

It is finded a number of tasks of complex objects controlling, that is not subject to formalization, of such complex objects, applied logico-linguistic model of controlling for definition methods of influence on the controlling object during arizing concrete situation. It is offered a questionaire as the method of expert queslioning for getting information from experts about conditions of rising, methods of influence on controlling object and the results of influence. Refs.: 4 titles.

The article is devoted to the problems of the motor transport processes planning using a building industry as an example. The new approach to the transport-accumulated processes planning is considered, classification of tasks, models and methods of optimization with a numeral example are offered. The model of the interval transportation graphs, which contains maximal time reserves with the purpose of providing organizational flexibility and external interruptions insensitivity is assumed as a basis. Tabl.: 6. Figs.: 14. Refs.: 5 titles.

In papers the universal model of differential estimation of knowledge for application in various systems of estimation is proposed. This model is simple for use at realization of adaptive testing of knowledge systems. At testing realization there is a possibility of a wrong knowledge estimation of the trainee because of a casual right answer input. In work the proposed test tasks forms from the point of view of guessing probability size are evaluated. Tabl.: 2. Refs.: 9 titles.

QUALITY, RELIABILITY, AND CERTIFICATION OF COMPUTER TECHNIQUE AND SOFTWARE

Design procedures of sufficiency of the ZIP, quantities of nonrestorable spare elements on the basis of use as theoretical model of failures of elements and a product of two-parametrical DN-distribution are presented. Refs.: 3 titles.

Calculation technique of availability and mean time between failures of geographically distributed system hardware is introduced. Technique is based on Markov process theory. Research can be used for evaluation and analysis of project reliability for designing or modernizing management-information system or another program-technical complex. Figs.: 3. Refs.: 5 titles.
